4 0

Answer:

x = 3.5

Step-by-step explanation:

Triangle to the right:

4^2 + x^2 = 8^2

16 + x^2 = 64

y^2 = 48

Triangle to the left:

x^2 + 6^2 = 48

x^2 + 36 = 48

x^2 = 12

x = sqrt(12)

x = 3.5

What name best describes this shape?
EastWind [94]

Answer: Quadrilateral

Explanation:

Any four sided polygon is considered a quadrilateral since "quad" means "four". You can think of a quad bike, which has four wheels, to help remember this math term.

Usually in problems like this, we'll be given information about if certain sides are parallel or the same length. However, we don't this info, so we cannot narrow down this classification anymore.

He repartido mi colección de canicas entre mis tres amigos. A thales le he dado 1/5 del total, a arquimedes un 1/3 del resto y p
elena-14-01-66 [18.8K]

Answer:

Ok, supongamos que en total hay N canicas.

1/5 de esas canicas se le dieron a Thales.

Entonces el resto ahora es:

1 - 1/5 = 4/5.

1/3 de esas canicas se le dieron a Arquimedes.

Entonces Arquimedes recibe:

(1/3)(4/5) = 4/15 de las canicas totales.

El resto, que eran 16, se le dieron a Pitagoras.

Ahora, las dos primeras entregas fueron:

1/5 + 4/15 = 3/15 + 4/15 = 7/15.

El resto seria:

1 - 7/15 = 8/15.

Y sabemos que el resto es igual a 16 canicas, entonces tenemos que:

(8/15)*N = 16.

De aca podemos calcular el numero total de canicas.

N = 16*(15/8) = 30

Esto quiere decir que inicialmente hay 30 canicas.

Thales recibe 30*(1/5) = 7 canicas.

Arquimedes recibe 30*(4/15) = 8 canicas.

Pitagoras recibe 16 canicas.

Assume that children is an integer variable containing the number of children in a community and that families is an integer var
kherson [118]

Answer:

Answered

Step-by-step explanation:

Children*1 d/ family

Integer division returns an integer value in most languages.

I am assuming "1d" is double precision 1, which turns the expression into floating point division, thus allowing an answer like 1.8.

it can also be written as

float(children)/float(family)
